Scott Alexander argues against judging polyamory based on memoirs or advice books, as these are often written by unrepresentative individuals.
Longer summary
Scott Alexander critiques a pattern in media where people generalize about polyamory based on memoirs or advice books. He argues that this is unfair, as such books are often written by people with relationship issues or narcissistic tendencies, not representative of the average polyamorous person. He extends this critique to other groups, suggesting that public representatives often poorly reflect the actual members of various communities.
